Nyob zoo, cov neeg nyeem muaj nuj nqis thiab cov neeg nyiam siv tshuab! Niaj hnub no, peb pib taug kev mus rau hauv keeb kwm thiab tseem ceeb ntawm optical fiber ntau technology. Raws li ib qho ntawm cov chaw muab kev pabcuam ntawm cov khoom siv kho qhov muag fiber ntau, OWCable tau nyob rau hauv lub hauv ntej ntawm qhov kev lag luam zoo kawg li. Cia peb dhia mus rau hauv kev hloov pauv ntawm cov thev naus laus zis tshiab no thiab nws qhov tseem ceeb tseem ceeb.
Hnub yug ntawm Fiber Optics
Lub tswv yim ntawm kev coj lub teeb los ntawm qhov nruab nrab pob tshab hnub rov qab mus rau lub xyoo pua 19th, nrog rau kev sim thaum ntxov uas muaj cov iav pas nrig thiab cov dej ntws. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1960 uas lub hauv paus ntawm kev siv tshuab fiber ntau niaj hnub tau tso. Xyoo 1966, British physicist Charles K. Kao tau theorized tias iav ntshiab siv tau los xa cov teeb liab teeb pom kev deb ntev nrog cov teeb liab tsawg tsawg.
Thawj Optical Fiber Transmission
Ceev ceev rau pem hauv ntej mus rau 1970, thaum Corning Glass Works (tam sim no Corning Incorporated) tau ua tiav thawj zaug uas tsis muaj fiber ntau optical siv cov iav purity. Qhov kev ua tiav no tau ua tiav cov teeb liab attenuation tsawg dua 20 decibels ib kilometer (dB / km), ua rau kev sib txuas lus ntev yog qhov muaj tiag.
Qhov tshwm sim ntawm Single-Mode Fiber
Thoob plaws xyoo 1970, cov kws tshawb fawb txuas ntxiv txhim kho cov fibers kho qhov muag, ua rau kev txhim kho ntawm ib hom fiber ntau. Hom fiber ntau no tso cai rau cov teeb liab qis dua thiab ua kom cov ntaub ntawv sib kis tau ntau dua nyob rau qhov ntev. Ib hom fiber ntau sai sai tau los ua cov pob txha ntawm kev sib txuas lus nyob deb.
Kev Lag Luam thiab Kev Sib Txuas Lus Boom
Xyoo 1980s tau kos lub ntsiab lus rau kev siv tshuab fiber ntau. Raws li kev nce qib hauv kev tsim cov txheej txheem ua rau tus nqi qis, kev lag luam txais yuav cov fiber ntau optic cables tawg. Cov tuam txhab kev sib txuas lus tau pib hloov cov kab hluav taws xob tooj liab nrog cov khoom siv kho qhov muag, ua rau muaj kev hloov pauv hauv kev sib txuas lus thoob ntiaj teb.
Internet thiab Tshaj
Hauv xyoo 1990, qhov nce hauv internet tau ua rau qhov kev thov tsis tau muaj dua rau kev xa cov ntaub ntawv ceev. Fiber optics ua lub luag haujlwm tseem ceeb hauv qhov kev nthuav dav no, muab cov bandwidth tsim nyog los txhawb lub hnub nyoog digital. Raws li kev siv internet skyrocketed, yog li xav tau kev kho qhov muag fiber ntau dua.
Kev nce qib hauv Wavelength Division Multiplexing (WDM)
Txhawm rau ua kom tau raws li qhov xav tau ntau ntxiv rau bandwidth, engineers tsim Wavelength Division Multiplexing (WDM) thaum xyoo 1990s. WDM thev naus laus zis tso cai rau ntau lub teeb liab ntawm qhov sib txawv wavelengths mus ib txhij los ntawm ib qho kev kho qhov muag fiber ntau, ua rau nws muaj peev xwm thiab ua tau zoo.
Hloov mus rau Fiber rau Tsev (FTTH)
Raws li peb tau nkag mus rau lub xyoo txhiab xyoo tshiab, lub hom phiaj tau hloov mus rau kev coj cov fiber ntau ncaj qha rau hauv tsev thiab kev lag luam. Fiber rau Lub Tsev (FTTH) tau dhau los ua tus qauv kub rau kev siv internet ceev thiab cov ntaub ntawv, ua kom muaj kev sib txuas tsis sib xws thiab hloov pauv txoj kev peb nyob thiab ua haujlwm.
Optical Fiber Niaj hnub no: Ceev, Muaj Peev Xwm, thiab Tshaj
Nyob rau hauv xyoo tas los no, optical fiber technology tau txuas ntxiv mus, thawb cov ciam teb ntawm cov ntaub ntawv xa mus. Nrog rau kev nce qib hauv cov ntaub ntawv fiber ntau, kev tsim khoom, thiab kev sib txuas lus, peb tau pom qhov nce ntxiv hauv cov ntaub ntawv ceev thiab muaj peev xwm.
Lub neej yav tom ntej ntawm Optical Fiber Technology
Raws li peb saib mus rau yav tom ntej, lub peev xwm ntawm optical fiber ntau zoo li tsis muaj kev txwv. Cov kws tshawb fawb tab tom tshawb nrhiav cov ntaub ntawv tshiab, xws li hollow-core fibers thiab photonic siv lead ua fibers, uas tuaj yeem txhim kho cov ntaub ntawv xa mus ntxiv.
Nyob rau hauv xaus, optical fiber technology tau los ntev heev txij li thaum nws pib. Los ntawm nws qhov pib txo hwj chim raws li kev sim lub tswv yim los ua tus txha caj qaum ntawm kev sib txuas lus niaj hnub no, cov thev naus laus zis zoo kawg no tau hloov pauv lub ntiaj teb. Ntawm OWCable, peb muaj kev txaus siab los muab cov khoom siv kho qhov muag pom tseeb thiab txhim khu kev qha zoo tshaj plaws, tsav cov tiam tom ntej ntawm kev sib txuas thiab txhawb nqa lub hnub nyoog digital.
